what are DRV
estimates of the energy and nutrients needed bud ifferent groups of healthy people
who were DRV set by
committee on medical aspects of food and nutrition policy (COMA)
when were DRV set
1990s early
what is the estimated average requirement
it is the level of nutrient set to satisfy 50% of the population- therefore around 50% will need less and around 50% will need more
what measurement is derived from the EAR
THE REFERENCE NUTRIENT INTAKE (rni)
what is the reference nutrient intake derived from
the estimated average requirement
how do we satisfy most the population without causing harm
by hvaing max and minimum values 2+- the standard deviation values of the EAR
how do we protect people from harm in regards to the reference nutrient intake
also have it 2+- the standard deviation
what is the reference nutrient intake also known as
the recommended daily allowance
